Air Cleaner
Foam Element: Clean and re-oil after every 25
operating hours.
Paper Element: Replace after every 100 operating
hours.
Note: Service the air cleaner more frequently
(every few hours) if operating
conditions are extremely dusty or
sandy.
Removing the Foam and Paper Elements
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Clean around the air cleaner to prevent dirt from
getting into the engine and causing damage.
Unscrew the knob and remove the air cleaner
cover (Fig. 22).
